2025 Cube Kathmandu Hybrid Slx 800 Electric Bike in Grey
You want dependable? The Kathmandu Hybrid SLX from CUBE gives you dependable. Equipped with Newmen Performance 30 wheels shod with Schwalbe Marathon Efficiency tyres, it'll keep rolling whether you're tackling potholed city streets or dusty country lanes. The adjustable stem, versatile dropper seatpost and Fox 34 AWL suspension fork all help keep the ride comfortable. The Integrated Carrier 3.0 is a tough, elegant and versatile way for you to carry what you need, and there's a full complement of included accessories, too. An PowerTube battery ensures there's enough juice to keep feeding the quiet Bosch CX drive and its up to 85 Nm of pedal assistance. And, with Shimano's XT hydraulic disc brakes and gears taking care of stop-and-go duties, you know you're in good hands.
The CUBE Kathmandu Hybrid's design is classically elegant – familiar, even – but it's stuffed full of innovation and clever touches. The neatly housed Bosch CX drive and PowerTube battery are just the start. Efficient Comfort Geometry is designed around a 100mm travel suspension fork, for better control even when the going gets rough. Integrated cables complement the frame's clean lines and help reduce the need for maintenance, while a UDH dropout is tough, versatile and future-proof. And, of course, there's an integrated chainguard mount and our tough, sturdy and exceptionally neat Integrated Carrier 3.0, so you can carry everything you need for your adventures.
